Should I go with the a833 conversion?

I just picked up an a833 OD out of a 77 Aspen wagon, I'm planning on swapping it into my automatic 318 powered 68 Valiant, but I'm not really sure if I can/should do the swap, I just couldn't say no to the deal I got on it, and I've never owned a manual car, and I want to have one. Are there any threads on here that have good info? Do any of y'all have good tips for doing this swap on a budget? I know its not gonna be cheap, but how reasonably can it be done?
